Following publication of an article showing that the corporation plans to outsource some IT systems despite being given a "red light" by the government's Gateway review process, solicitors Trowers & Hamlins wrote to Computer Weekly insisting that the newspaper does not "publish any further confidential information relating to the Housing Corporation in any way whatsoever".
The letter goes on to ask Computer Weekly to disclose the source of the information.
Computer Weekly, which has won a Freedom of Information Award for its investigative reporting, has refused to comply with these requests.
"We believe it is in the public interest that a body responsible for allocating more than £1.3bn a year to housing associations is held accountable, should bad project management squander taxpayers' money," said editor Karl Schneider.
The publication has informed Trowers & Hamlins and is awaiting a reply.
Further details of problems at the corporation's IT department have emerged this week in the shape of a bungled disaster recovery exercise, when data tapes were lost on the Tube.
